Abstract
A system and method for detecting, identifying, and fixing the location of the source of an acoustic event. The inventive system includes: a plurality of sensors dispersed at somewhat regular intervals throughout a monitored area; a communication network adapted to deliver information from the sensors to a host processor; and a process within the host processor for determining, from the absolute times of arrival of an event at two or more sensors, a position of the source of the event. Acoustic events are detected and analyzed at each sensor so that the sensor transmits over the network: an identifier for the sensor; an identifier for the type of event; and a precise absolute time of arrival of the event at the sensor. In a preferred embodiment, the system also identifies the type of weapon firing a gunshot.

15. A method of processing instructions associated with directing weapon fire towards the location of an acoustic event, the method comprising:
-
networking at least three sensors across an area to be monitored, wherein each of the at least three sensors comprises a microphone for detecting the acoustic event, and wherein the location of each of the at least three sensors is known; performing time of arrival processing of the acoustic event; determining an approximate location of a source of the acoustic event as a function of arrival time and sensor location data; and processing instructions associated with providing information for directing return fire as a function of the approximate location.
